We solve the Eliashberg equations exactly for anisotropic interactions projected onto extended s-wave and d-wave states. The resulting density of states for a gap with nodes (s-or d-wave) yields a nuclear spin relaxation rate which has almost no Hebel-Slichter peak. We calculate ~F, He, and ~C for d
Wide variety of spectra of high-Tc superconductors is explained systematically by the proximity electron tunneling spectroscopy of dx2.y2-wave superconductors. The existence of ZBCPs in many high-Tc superconductor junctions is one of the evidences for d-wave paring states in this material.
